No full textChirurgia della parete addominale
No full textLa chirurgia della parete addominale è un campo d’azione quotidiano per moltissimi chirurghi. Negli ultimi anni, alle tecniche ormai consolidate della chirurgia classica se ne sono affiancate altre, innovative, derivanti dall’impulso che la chirurgia laparoscopica e mini-invasiva hanno esercitato sulla chirurgia generale. Quest’opera si rivolge tanto ai chirurghi in formazione quanto ai più esperti, nell’intento di fornire ai primi un mezzo facile, ma completo ed esauriente, per aiutarli nello studio, e ai secondi una sintesi delle tecniche a disposizione. Nella cura delle ernie e dei laparoceli sono presentate sia le tecniche classiche sia quelle, in costante espansione, della chirurgia laparoscopica. Ampio spazio è dedicato alla chirurgia protesica e ai materiali sia protesici che di fissazione.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Laparoscopic appendectomy, surgical technique in 100 cases
No full textWe present our experience with laparoscopic appendectomy. From July 1992 to September 1995 we adopted this technique for 100 non selected patients; age was 23 years (range 11-63). Five patients had associated procedures: 4 right groin hernia repairs (TAPP) and 1 cholecystectomy. In 18 patients we have found a gynaecological disease. Conversion to conventional laparotomy was required only in one patient. We had 2 minor complications, acid a major one: a hemoperitoneum (1 liter that we have attributed to wound of the epigastric vessels by a trocart. The postoperative course was better than after open surgery: patients were discharged 2 days (range 1-10) after the operation, and had minimal postoperative pain. We finally present an instrument created by us which can be used to execute any type of extracorporeal ligatures. Laparoscopy is an excellent way to diagnose other intraabdominal diseases: it allows a much more thorough exploration of the entire abdomen and pelvis than a Mc Burney incision
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
